My basic concepts of all the topics were clear and I also prepared HR questions through mock interviews. I practised all the basic to medium coding question before interview.

Coding problem1
1. Maximum Subarray Sum
Moderate
25m average time
75% success
0/80
Asked in companies
Given an array of numbers, find the maximum sum of any contiguous subarray of the array.
For example, given the array [34, -50, 42, 14, -5, 86], the maximum sum would be 137, since we would take elements 42, 14, -5, and 86.
Given the array [-5, -1, -8, -9], the maximum sum would be -1.
Follow up: Do this in O(N) time.
Problem approach
I solved it using simple approach of O(n2) complexity. Interviewer didn't asked me for the efficient approach, as he looked satisfied and moved to the question.

Coding problem2
This is a cultural fitment testing round. HR was very frank and asked standard questions. Then we discussed about my
role.
1. Basic HR Question
Why should we hire you ?
Problem approach
Tip 1 : The cross questioning can go intense some time, think before you speak.
Tip 2 : Be open minded and answer whatever you are thinking, in these rounds I feel it is important to have opinion.
Tip 3 : Context of questions can be switched, pay attention to the details. It is okay to ask questions in these round,
2. Basic HR Question
Why are you looking for a job change?
Problem approach
Tip : For an experienced professional seeking a change, this is a common question. The easiest method to respond to this question is to state that you are leaving your current work in order to advance your career. Make sure you don't criticize or speak poorly about the company where you now work.
